This is part of what I love about *nix; there's so many different ways
to accomplish a task.

Thank you for the additional perspective.  I have just enough experience
with the OS (about 10 months) to understand the power but not enough to
know how to use it properly.  In the past, I would just do them one at a
time until I was done but now I'm forcing myself to learn how to do it
right.  And because I'm learning, I appreciate seeing the different ways
available to do things.

Thanks,

Drew
